Description
Technical Field
The invention relates to the technical field of ship construction, in particular to a ship high-stress node structure.
Background
In modern ship design, in order to save oil consumption, increase cargo capacity and reduce construction cost, the idea of lightweight structure design is generally pursued. However, for the safety of ship operation, it is impossible to reduce the plate thickness and reduce the structural members at will under the requirements of the regulations and the convention, and therefore, it is an important objective of structural design to reduce the structural weight as much as possible under the requirement of ensuring the compliance with the regulations and the convention.
When a ship structure is designed, the node at the sudden change of the structure often has larger stress, for example, the node at the junction of the lower inclined side plate and the inner bottom plate or the inner longitudinal wall plate and other similar nodes have larger profit. Taking the joint at the intersection of the lower inclined side plate, the platform plate, the inner longitudinal wall plate and the rib plate of the LNG transport ship as an example, the traditional design mode of the joint at the position is that the platform plate extends out of the inner longitudinal wall plate, the lower inclined side plate is connected to the intersection of the platform plate and the inner longitudinal wall plate, when the stress of the joint at the position is too high, the thickness of the adjacent area plates at the joint is generally increased to reduce the stress, or the material grade of the adjacent area plates at the joint is improved to improve the allowable stress, and when the stress at the joint cannot be reduced below the allowable stress by the methods; in the case of such excessive stress, small ribs or brackets are usually added at 1/4 or 1/2 to reduce the node stress, which increases the structural weight, especially in special cases, such as single-tank loading of a double-tank tanker, which causes the node stress to be too high, and it is difficult to reduce the stress to the allowable range by only increasing the plate thickness or the small ribs, which is difficult to meet the requirement of the node design.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and design a ship high-stress node structure, which can meet the requirement of allowable stress, obviously reduce the weight of the structure and facilitate on-site manufacture and installation.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a ship high-stress node structure comprises a horizontally arranged platform plate, a longitudinal cabin wall plate longitudinally and vertically arranged on the platform plate, an inclined side plate obliquely arranged at the intersection of the platform plate and the longitudinal cabin wall plate, a rib plate mutually perpendicular to the platform plate and the longitudinal cabin wall plate and a toggle plate fixedly connected with the lower surfaces of the rib plate and the platform plate respectively, wherein the lower end of the longitudinal cabin wall plate extends out of the connection part of the longitudinal cabin wall plate and the platform plate by 30-50 mm, and a first cutting groove for enabling the longitudinal cabin wall plate to pass through is formed in the corner of the rib plate; the two toggle plates are respectively a left toggle plate and a right toggle plate, the left toggle plate and the right toggle plate are respectively arranged on two side walls of the rib plate, free edges of the left toggle plate and the right toggle plate are both arc-shaped, the lower end surface of the left toggle plate is an inclined surface, and the lower end surface of the right toggle plate is fixed on the reinforcing rib; and second cutting grooves are formed in the corners where the left toggle plate and the right toggle plate are connected with the rib plate and the platform plate.
The toggle plate and the longitudinal cabin wall plate are positioned on the same plane.
The invention has the following positive beneficial effects: the invention has simple structure and convenient field manufacture and installation, can make the stress of the node transmitted downwards by extending the lower end of the longitudinal cabin wall plate from the connecting part of the longitudinal cabin wall plate and the platform plate by 30-50 mm, and can obviously reduce the stress concentration condition of the node by arranging the rib plate and the toggle plate, thereby greatly reducing the stress of the node, reducing the plate thickness of the longitudinal cabin wall plate and the thickened plate of the inclined side plate around the node, even not arranging the thickened plate, greatly reducing the number of the toggle plate and effectively reducing the structural weight of the ship.

Detailed Description
In order that the objects, aspects and advantages of the invention will become more apparent, the invention will be described by way of example only, and in connection with the accompanying drawings. It is to be understood that such description is merely illustrative and not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The embodiment is described with reference to fig. 1, and the high-stress joint structure of the ship comprises a platform plate 1, a longitudinal bulkhead plate 2, a diagonal side plate 3, a rib plate 4 and a toggle plate.
The platform board 1 level sets up, and vertical cabin wallboard 2 vertically sets up on platform board 1, and the slope of slope side board 3 sets up in the intersection of platform board 1 and vertical cabin wallboard 2, and slope side board 3, vertical cabin wallboard 2, platform board 1 constitute a node jointly. In order to reduce node stress, the lower end of the longitudinal bulkhead plate 2 extends out 30-50 mm from the connection part of the longitudinal bulkhead plate and the platform plate 1, meanwhile, rib plates 4 are arranged on the platform plate 1 and the longitudinal bulkhead plate 2, and the rib plates 4 are arranged on the rib plates 4 and are both vertically arranged. The ribbed slab 4 is perpendicular to the platform plate 1 and the longitudinal cabin wall plate 2, and the toggle plate is fixedly connected with the ribbed slab 4 and the lower surface of the platform plate 1 respectively. The toggle plate is butted with the longitudinal bulkhead plate 2, and the toggle plate and the longitudinal bulkhead plate are positioned on the same plane.
